摘要： Time sequential information is written to a first light-to-light conversion element, and the thus-written time sequential information is thereafter written from the first light-to-light conversion element to a second light-to-light conversion element in the form of two-dimensional information. With this arrangement, the time sequential information can be converted with high resolution to the two-dimensional information in real time operation without involving a brightness gradient or shading.

摘要： A voltage is electrostatically induced at a sensing device in correspondence with a surface potential of a measured object. In the case where the sensing device uses a field effect transistor in transferring detected information, there are some factors decreasing the accuracy of detection. Various new arrangements prevent such decreases in the accuracy of detection. In the case of the surface potential of the measured object corresponds to an optical image, new arrangements ensure accurate detection of the optical image. In some cases, color component signals are obtained on the basis of a detection signal.
